Error: Couldn't find per display information - JDK 1.6 on Linux
Running Spark on java 1.6.0 in Linux always gets the error:
Error: Couldn't find per display information
It is caused by a bug in jdic tray icon library. Latest version of jdic has solved this problem. https://jdic.dev.java.net/servlets/ProjectDocumentList?expandFolder=4183&folderID=5497
Notice that this problem did not happen in java 1.5. Some linux (as Fedora) have problems running spark with Java 1.5, after login, the windows is blank.
Now we use java 6!
Thanks all poeple for help!
